Whenever you scroll to an area you haven't downloaded, the area will start downloading automatically.

Only works at high zoom levels (but not very high zoom levels).

It can be slow in big cities or other places with a lot of data.

Don't forget that you can turn this plugin on and off. Sometimes it's useful to turn off temporarily if you just want to draw something across a large area without taking the time to download everything else around.

Especially useful if you like drawing in a vector graphics program like Inkscape or Illustrator.

A major benefit to using a vector graphics program is the ability to draw using a wide range of more natural and more versatile tools. For example you can draw shapes by simply dragging your cursor around the screen, rather than needing to click each and every point along the way.
